Cinderi, the frozen world
Cinderi is the fifth planet in the Hessdalen system, and is the only terrestrial planet positioned beyond the asteroid belt.
It was named by Liandean astronomer Berinjide Eiffeno in 468 PCC, and it has captured the attention of Hessdalenians for centuries.
Cinderi is the only terrestrial planet in the system besides Hessdalen to possess its own magnetic field. This protects the planet from solar radiation, and allows it to hold on to a stable atmosphere.
Cinderi is home to huge ammounts of water. Nearly the entire surface is covered in it. Except this water is locked in a frozen state, because Cinderi is located outside of the habitable zone. The constant frigid temperatures makes the possibility of there being life on Cinderi very low, despite being Earth sized, having a magnetic field, water, and a good atmosphere.
Due to Hessdalen's ring system, leaving their home planet has been a very difficult task for humans. No spacecraft, manned or unmanned, has ever left the planet. So Cinderi has only been observed from afar using telescopes. If humans ever leave Hessdalen, Cinderi will be the first planet they explore.
